Abstract: PURPOSE: A blade noise measuring system provides accurate data by measuring properties with respect to noise under various conditions of a blade. CONSTITUTION: A blade noise measuring system(100) comprises a blade rotating unit(110), a noise measuring member(120), a photographing member(130), a control panel, and a power source panel. The blade rotating unit rotates the blade, thereby generating noise. The noise measuring member measures the noise generates while rotating the blade. The photographing member photographs an operation state of the blade rotating unit. The control panel controls a rotating speed of the blade rotating unit, a rotating time, and a pitch angle of the blade. The power source panel supplies power to the blade rotating unit. The blade rotating unit, the noise measuring member, and a photographing member are installed inside of a dead room(140).

Abstract: A thermal switch is provided to control a temperature accurately by thermally separating a high temperature part and a low temperature part from each other to reduce an influence according to a heat capacity of a high temperature part. A thermal switch includes a main panel(102), a tunnel(104), an air discharge groove(106), and a fluid storing groove(108). The tunnel penetrates a top surface and a bottom surface of the main panel. The air discharge groove is prepared on the top surface of the main panel and is connected to one upper end of the tunnel. The fluid storing groove is positioned in a lower portion of the tunnel and stores a heat transfer fluid. The thermal switch adjusts a height of the heat transfer fluid in the tunnel to control heat transfer between a heat source and a heat sink. The height of the heat transfer fluid in the tunnel is adjusted by an expansion body(110) which is prepared in the fluid storing groove.
